Patented Dec. 17, 1929 UNITED STATES PATENT oFFIeE JOHN WALDHEIM, OF'ELLZABE'lI-, NEW JERSEY, ASSIGNOR TO UNDERNOOD 'ELLIOTT FISHER COMPANY,OF NEW YORK, N. Y., A CORPORATION OF DELAXTV'ARE TYPEWRITING MACHINEApplication filed August 29, 1923. Serial No. 659,913.

rlhis invention relates to machines for typing upon continuouswork-webs, each comprising a plurality of plies usually provided withsuccessive printed forms superposed in 5 register,the plies beingseparate in some cases and in other cases being joined at their sideedges. The invention is in the nature of an improvement on my Patent No.1,362,547, dated December 14, 1920.

In said patent the composite web or workweb, comprising the web-plies,is introduced substantially horizontally to the bottom of the platen,over a table or support on which the carbon-carrier isy mounted forreciprocation, and over a substantially horizontal paper-table tosupport the web between the forward end of the carbon-carrier supportand the bottom of the platen, thus eliminating the binding of theweb-plies and interleaved carbon-sheets dueto the usual bends in the webat the rear of the platen. Provision is also made for reducing thebending of the web-plies at the delivery side of the platen by swingingforwardly to a limited extent a paper-table and anassociatedleading-.end-gaging device independently of `the platen. As aresult of the arrangement just described, it becomes unnecessary todisplace the plat-en in the usual mannerpreparatory to effecting arelative shifting of the webplies and interleaved carbon-sheets.

An object of the present invention is to provide improved means of thesame general Y nature as that described for effecting such relativeshifting ofthe webplies and carbonsheets without displacement of theplaten o1' forward swing of the paper-table and gaging means at thedelivery side of the platen.

According to the form of the invention herein disclosed, theweb-and-carbon-sheetintroducing means at the introductory side of theplaten is substantially the same as in said patent, and provision ismade vat the delivery side of the platen of a paper-table fixed to theplaten-frame, and of a gaging device having two gages at a suitabledistance apart such that, when, after the lrelease of the feed-rolls,the web-plies and interleaved carbon-sheets are shifted rearwardly bythe carboncarrier to withdraw the leading ends of the carbon-sheets`from control by the platen, the feedrolls may be cast on, the web*plies advanced independently of the carbonsheets by the platen to bringthe leading ends of the webplies into alignment with the nearest gage,and then the web-plies and carbonsheets may.'` beV advanced togetheruntil the leading edges of the web-plies are aligned with the other gagepreparatory to tearing olf the irst set of forms and typing on thesecond set of forms.

Provision may also be made of one or more side gages to be set insuitable perforations in the rear paper-table over which the webpliespass from the carbon-carrier support to the bottom of the platen.Freferably each side gage has a forked lower end to permit springing ofthe tines when forced into position and consequent binding to maintainthe side gage in such position.

Other features and advantages will hereinafter appear.

Figure 2 is a view similar to Figure 1, but showing the carbonssheetsand web-plies in the positions assumed when retracted by thecarbon-carrier after completing the typing on a set of forms and castingolf the feed-rolls.

Figure 3 is a View similar to Figure 2, but showing the web-pliesadvanced relatively to the carbon-sheets by the platen and cast-onfeed-rolls, the carbon-sheets being held against forward movement bymeans of the carbon-carrier.

Figure 4 yis a view similar to Figure 3, but showing the web-plies andcarbon-sheets advanced by the platen and feed-rolls from their Figure 3positions to positions suitable vfor tearing off the typed forms.

Upon depression of keys (not shown), type-bars 11 are swung upwardly andrearwardly to cause types l'thereon to strike a platen 13, journaled bymeans of an axle 14- inthe ends 15 of a platen-frame 16. The ends 15 ofthe platen-frame are joined at the rear by a transverse member 17 andbeneath the platen by means of a rod 18, on Vwhich are mounted levers19, carrying rea-r and Vfront feed-rolls land 21', respectively, the

effectiveness of the feed-rolls being controlled by means of acontrolling shaft 22 extending between. downwardly-projectingi ends 23"of the levers 19. The' controlling shaft 22 is controlled in the usualmanner by acastfof linger-pieceT241 connected., thereto by means oi'alink-25, pivotedtoanarrnQG;iiced on the shzii't'22.

Y lnthe-form of the' invention hereinzdisclosed, Yprovision, ismade ofl apaper-table 69',`

at-the delivery' side of: the.l platen, having f downwardlyturned ears4or brackets 6.1 atf tached to the ends 15lofthe; platen-frame` 16,

andl having attached theretoatr: its` rea-r a gagexbar or staff 62,'onxwhichfis slidably mounted a gag-ingqdevice: 63' comprising a:

gage 64!` to= gagetfhee forward ends of the work-plies when advancedrelatively'to` lthe carbonsheetsV withI the latter. in their retractedpositions and.A al second gage 65 to. determine the initial; position ofthe: Web-` plies and carbonfsheets for beginning the typ-ing ofanothenset of; forms;v The gaging device 65E-adjustable along thegage-bar 62 to correspond tofdiilerent lengthsof forms may be secured;atany position along `said gageLbar 62 by'meansoff a set-screw 66.

It' is'desir-ab'le tobe able toluse the Vgaging device with short:forms, and,` as herein disclosed,- this i resultr is' obtained byproviding@l the sta-fil 62lw=ith an offset 68 to. bring the upper endofthe statt tofthe front: ot the plane of the table 60 and by providingacutout 69 in the,` table. to receive said:v gage. 64. lVhen itisdesired to type onthe workfweb 41, the forward end of t'heweb'isfpassedover the guidef' and forward Voverthe. table or extension 49, andthe-carbonf-sheets 40jv are 'interleaved' between the pliesV 39-Withtheir leadingt ends tothe rear` of thefleading ends ofv the web-plies3.9i The forward ends'of the web-plies 239i may thenbe inserted be-vneath: the platen anda' advanced by the platen andl feed-r0lls unt-ilt-hefleadingI edges Ot the plies 39 are in alignment with the gage 64,the position: of which is determined by adjnsting thev gagingdevice 631with the gage 65-ata distance from a knife 70 equal to the lengtl'iy ofoneloff thelforms onthe web'41r. f Y

During suchl advancek of the web-plies39, the carbon-carrier 45 is heldby means offa handle'-u 71j thereon inits rearmost'fposition determinedby a stop 72. In this connection it'should be not-edy that thecarbon-sheets 40 iss are of such length that, when the carbonearrier isin its rearmost position, the leading ends of the carbon-sheets arepositioned substantially as shown in Figure 3. v

After positioning the web-plies 39 and the carbon-sheets 40, as shown inFigure 3, the carbon-carrier t5 is released and the webplies andcarbon-sheets advanced by the platen and feed-rolls to the positionsindicated in Figure l.

The first set of forms is then severed by the knife 'TO and thereafteris in readiness for typing on the second set of. forms. After`completing the typing on the second set of forms with the web-plies andcarbon-sheets positioned substantially as indicated in Figure l, thefeed-rolls 2O and 2l are cast olf, by means of the finger-piece 24, andthe webplies 39 and carbon-sheets retracted, by means of the handle 7lon the carbon-carrier, to the position shown in Figure 2. The feedrollsare then cast on and the web-plies advanced bythe platen to their Figure8 positions, the carbon-sheets being held in their retracted posit-ionsby means of the handle 7l. The handle 71 is then released and theweb-plies and carbon-sheets advanced to their Figure 4l positionspreparatory to severing the typed forms and starting the typing on thenext set of forms. In this connection it should be noted that thedistance between the gages G4 and 65 is equal to the distance around thebottom of the platen from the leading-edge positions of thecarbon-sheets in Figure 8 to their leading-edge positions in Figure 4l.

Although the manner just described of positioning` the web-plies andcarbon-sheets to start typing appears to be the most practicable, itshould be understood that such positioningmay be done in other ways, as,for example, by positioning the forward edges of the nrst set of formsthe proper distance beyond the ends of the carbon-sheets and positioningthe carbon-sheets and webplies as shown in Figure 2. Obviously, if thismethod is followed, typing may be effected on the first set of forms.

To assist in guiding the composite web to the proper position on theplaten, provision may be made of one or more side gages 73 positioned insuitable perforatirmsv in the rear paper-table 36. As shown in Figure l,each of the gages 73 is provided with a slot 7a extending toward itsupper end to facilitate the springing towards or from each other of thetines 7 5, so that, when the reduced ends 76 are pressed into suitableopenings in the paper-table 36, the resiliency of the tines willtend tohold the gage in set position.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.

Having thus described my invention, I claim:

l. A gage-device for a continuous billing typewriting machine of theclass described having a platen-frame, a platen, and a papertable fixedon said platen-frame at the delivery side of said platen, including anupwardly-extending gage-bar fastened on said paper-table, an upper.transverse gage adjustable along said gage-bar and projecting forwardlytherefrom, and a lower gage consisting of the lower end of a bar, whichbar is fastened to said upper gage and extends downwardly along saidgage-bar and parallel thereto a short distance to one side and in therear thereof, whereby the leading end of a work-piece in said machinemay be first gaged by the lower gage and thereafter be convenientlyadvanced past said lower gage to be gaged by the upper gage.
